9.3.6. Upgrades from a Staging Directory

This process must be run from the staging directory in order to run properly. Determine where the current software was installed from.

shell> tpm query staging

This outputs the hostname and directory where the software was installed from. Make your way to that host and the parent directory before proceeding. Unpack the new software into the /opt/continuent/software directory and make it your current directory.

shell> tar zxf tungsten-clustering-5.1.0-187.tar.gz
shell> cd tungsten-clustering-5.1.0-187

Before any update, the current configuration must be known. If the $CONTINUENT_PROFILES or $REPLICATOR_PROFILES environment variables were used in the original deployment, these can be set to the directory location where the configuration was stored.

Alternatively, the update can be performed by fetching the existing configuration from the deployed directory by using the tpm fetch command:

shell> ./tools/tpm fetch --reset --directory=/opt/continuent \

This will load the configuration into the local staging directory. Review the current configuration before making any configuration changes or deploying the new software.

shell> ./tools/tpm reverse

This will output the current configuration of all services defined in the staging directory. You can then make changes using tpm configure before pushing out the upgrade. Run tpm reverse again before tpm update to confirm your changes were loaded correctly.

shell> ./tools/tpm configure service_name ...
shell> ./tools/tpm update

This will update the configuration file and then push the updates to all hosts. No additional arguments are needed for the tpm update command since the configuration has already been loaded.


The tpm update command may cause a brief outage while restarting the connectors. This will occur if you are upgrading to a new version You can avoid that with:

shell> ./tools/tpm update dataservice --no-connectors

The connectors must be updated separately on each server by running:

shell> tpm promote-connector
